1. The dean of students at CMSU has learned about the undergraduate survey and has decided to undertake a similar survey for graduate students at CMSU. She creates and distributes a survey of 14 questions and receives responses from 44 graduate students (stored in GradSurvey). For each numerical variable in the survey, decide whether the variable is approximately normally distributed by
